A marsupial in wolf's clothing - First 3D digital models reveal convergent evolution

Researchers from Museums Victoria and the University of Melbourne have CT scanned all 13 known Tasmanian tiger joey specimens to create 3D digital models which have allowed them to study their skeletons and internal organs, and reconstruct their growth and development. This has revealed important new information about how this unique extinct marsupial evolved to look so similar to the dingo, despite being very distantly related.

Fungal-like fossils found in 2.4 billion years old seafloor lava

Researchers have discovered microfossils resembling fungi in lavas that erupted on the seafloor 2.4 billion years ago, representing the oldest evidence of fungal life.

The new paper, published in Nature Ecology and Evolution today, suggests that fungi not only emerged much earlier than suspected but also evolved beneath the sea rather than on land.

Until now, the fossil evidence for cavity-dwelling fungi only extended back 46 million years, but the new discovery potentially extends that record by 2400 million years.

Frozen in Time: Prehistoric life in Antarctica - new book


In its transition from rich biodiversity to the barren, cold land of blizzards we see today, Antarctica provides a dramatic case study of how subtle changes in continental positioning can affect living communities, and how rapidly catastrophic changes can come about. Frozen in Time reconstructs Antarctica’s evolving animal and plant communities as accurately as the fossil record permits.

To Believe or Not to Believe---That is the Question---Dawkins, Hedges and Human Nature

Religion comes in many guises. Orthodox or established belief systems have no monopoly in delusional thinking. In fact, it is my contention that such thinking is central to our makeup, and that efforts to eradicate it, however well merited, are futile. That is why we are doomed. We need comfort as well as truth, and are programmed to ignore or deny long-term threats. Delusional thinking gets us through the night, but it will not get us through this century.

Human destiny revisited ?

An Italian evolutionary meta-theory says planetary health depends on humans and that humans will in the future free themselves from the unbearable weight of the world by stopping reproducing. "Si spegne, signori, si chiude” Review by Marisa Cohen
